What is the difference between load and line wires?
Load lines are one form of wiring specifically used in homes that results in less liability and claim responsibility when things go awry.
Load lines are designed to offer protection for the home’s inhabitants against accidents, injury or death due to electrical dangers. In short, they’re a means of legally “availing” oneself from liability by reducing risks pertaining to electricity (i.e., who you might be able to sue if someone gets electrocuted by touching a bare wire). Utilization of load lines isn’t recommended unless there is an emergency or something specific going on–they may actually increase your risk of death when inspected on an annual basis and up-to-date with code.
